GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

Jaguar I-Pace vs. Tesla Model 3 and other EVs: How they compare on paper

The 200-mile club of electric vehicles is really growing. The most recent member is the Jaguar I-Pace, the company's first pure EV. It promises luxury, performance, style, and most important, good range. Nearly as recent is the Hyundai Kona EV, and while it doesn't promise luxury or performance like the Jaguar (it's also smaller), it does pack impressive range. With the introduction of both of these electric cars, we thought we would see how they compare against each other, and the other two big names in high-capacity electric cars: the Chevy Bolt EV and the Tesla Model 3. This isn't intended to be a direct, apples-to-apples comparison, as the four are quite different. If anything, they break into two groups: bigger and more luxurious, and smaller and less expensive. Then again, the number of vehicles with this electric range is small and comparisons to EV's with less range wouldn't be too kind to the other guys. If you want to learn more about these EVs, and compare them with other cars, be sure to check out our Car Finder and comparison tools. Horsepower and torque There is one clear winner here, and that's the Jaguar I-Pace. It packs a whopping 394 horsepower and 512 pound-feet of torque. That comes through a pair of electric motors (one at the front, another at the rear) that provide the Jag with all-wheel drive, the only one of these vehicles to offer it (at the moment). Altogether, it allows the I-Pace to have the best 0-60 mph time of 4.5 seconds. At the other end of the spectrum is the Hyundai Kona EV. It's front-drive, like the Bolt EV, and has effectively the same amount of horsepower as the Chevy at 201 horsepower, but its 0-60-mph time is almost a second slower. And the low-range version of the Kona, excluded because it doesn't go more than 200 miles between charges, is slower still. The Tesla Model 3 is the only vehicle with rear-wheel drive, and with a 0-60 mph of 5.1 seconds for the Long Range model, it is still very quick. Range and energy use Frequently, the all-consuming question with electric cars is, "How far can I go on a charge?" And to go the farthest, you need the long-range Tesla Model 3. It can go 310 miles. It has the added advantage of being able to use the network of Tesla Supercharger stations, though they are pay-per-use with the Model 3. Even the lower capacity Model 3, with just 220 miles of range, can use these stations.

GMC Envoy could be returning as GM files for 'Envoy' trademark

The GMC Envoy could be on its way back, if a recent GM trademark filing is any indication of the future. To be exact, GM's trademark filing is for the name "Envoy," and is applicable to "motor vehicles, namely, sport utility vehicles, engines therefor and structural parts thereof." A victim of the recession and high gas prices, the original Envoy – related to the Blazer, and more recently the TrailBlazer and similar GM SUVs – was discontinued after the 2009 model year. In today's SUV-happy market of low gas prices, unearthing the somewhat familiar Envoy name makes a certain amount of sense. As soon as gas prices start trending in the other direction, we'll all be saying the opposite, though. What this SUV will take shape as is the big question now. With the Chevrolet Blazer well and truly on its way, there's every reason for a GMC version of Chevy's stylish new crossover sporting the Envoy name. Another, less likely, possibility is a Traverse-sized vehicle to slot between the shorter Acadia (10 inches shorter than the Chevy Traverse) and the body-on-frame Yukon. GM could come out of left field and make the Envoy a Buick too. It fits the bill with the "En" beginning, and Buick undoubtedly has crossovers in the works. We think that's even more unlikely, but it's important to remember that we're still in the speculation phase. Soon we'll drive Chevy's new Blazer, and perhaps have more news then. Check in next week for that. Related video:
